<info><![CDATA[

It can be useful at times to show and hide multiple columns together - i.e. grouping them together. Groupings are defined by the `groups` array. Create a group button by naming it (using the `title` option) and specifying by index which columns belong to it (using the `columns` option).

Note also that this ability to create groups can be used in combination `exclude` to remove individual columns from the list (should you wish them to only be used in the groups), or set `exclude = [ 'all' ]` to show only the grouping buttons (i.e. individual column control buttons will not be shown).

For full information about the ColVis options, please refer to the [ColVis options documentation](//datatables.net/extensions/colvis/options).
